Anti slip floor coating is ideal for commercial kitchens, butchery shops, fish shop, restaurant, bars and any areas which are exposed to water or spills.
There are primary ways to introduce grit (anti-slip) in to coatings is to mix the grit directly in to the coating.
The second is apply the coating & then immediately sprinkle the grit on top. It is either completed as a light random sprinkling which is then rolled or brushed in to the wet coating.
A slight alternative to the sprinkle/broadcast technique is to make use of sugar or salt as the sprinkled on grit. After the coating as hardened the sugar or salt is dissolved away. It leaves a pleasant looking surface, but in lieu of grain high points the pattern is negative (i.e. consists of ‘holes’). The grain holes can fill with dirt. Also, the soft coating my wear down quickly.
The third & most pretty & professional looking is a ‘broadcast’ where the whole painted surface is buried 100% with the grit as soon as the applied coating has level itself out. Know as ‘broadcast to excess’ or ‘broadcast to refusal’ the layer of grit is allowed to ‘sit’ until the coating gets hard. Usually a sealing topcoat is then applied to lock in the grit grains (thus a two coat technique).
1) add something to your paint or epoxy prior to rolling or brushing it onto the surface.
The mix-in technique works best with coatings that contain plenty of solvents or water (including water-based floor epoxies), but can be used with solvent free coatings as well. It does not work so well when the grit is sand. The heavy sand tends to settle quickly in the roller pan, thus most mix-in grits are made from lighter materials that will stay suspended in the coating for at least a couple of minutes.
With this technique matching the size of the grit to the thickness of the coating is vital. With narrow paints, polyurethanes. etc. plenty of fine additives like our walnut grit, products sold at paint stores, etc. will work fine. The grits used in these solvent rich coatings are very fine grained (larger grain sizes tend to ‘ball up’)
However, with epoxies (which are usually thick to start with & don’t ‘thin’ as they dry, most grits as they will get ‘lost’ in the coating. Thinner and/or solvent based coatings, as mentioned above, can use finer grit without the grit getting lost. Our larger rubber grit works with the thick epoxies.
Bottom line, match the grit to the paint. For boats etc. use a grit that you or future owners can sand off in the work of some future overhaul. That means don’t use sand. Also think carefully about using sand with this technique as it is so heavy it will sink to the bottom of the paint bucket (solution – mix well before every brush/roller load).
The âfeel of these anti slip surfaces is like that of a fine sandpaper – definitely rough but still fine grained (like what you might expect on a shower floor). Usually the distribution of the grit is not random. A person can usually see the original brush strokes due to the trail of grit grains left behind.
Commercial anti-slip coatings with the grit already mixed in tend to make use of much more grit in them than most owners would think about. In fact, these commercial products often require a squeegee or putty knife to apply, they are that thick with grit. This helps give a uniform appearance to the anti-slip coating.
